OTTO KAUFMAN, OF YOUNGSTOWN, OHIO.

MANTLE-SHAPING MACHINE FOR INVERTED MANTLES.

To all whom it may concern Be it known that I, O'r'ro KAUFMAN, a citizenof the United States, residing in the city of Youngstown, county ofMahoning, and State of Ohio, and whose post-office address is care ofthe Block Light Co. in said city, have invented a new and usefulImprovement in Mantle-Shaping Machines for Inverted Mantles, of whichthe following is a specification.

The object of my invention is to provide a machine of this class, inwhich a number of mantles may be simultaneously and automatically shapedand burnt, so that an attendant need do nothing more than insert andremove frames containing the mantles. This object is accomplished by myinvention, one embodiment of which is hereinafter set forth.

For a more particular description of my invention, reference is to behad to the accompanying drawings, forming a part hereof, in which-Figure 1 is a front elevation of the machine embodying my invention.Fig. 2 is an end elevation of the same. Fig. 3 shows details of theautomatic and intermittent driving mechanism, the view being a planview. Fig. 4 is an end view of the structure shown in Fig. 3. Figs. 5 to9 inclusive show the sprocket and clutch mechanism, the sprocket beingthe element that receives power from a suitable source, not shown. Figs.10 to 12 inclusive show details of the stop mechanism.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

My improved machine 1 is provided with suitable legs 2 and a table 3.The table 3 carries suitable standards 4 which are united at their upperextremities by means of a suitable gas drum 5, which may be a pipe orany other suitable structure and from this hang suitable pipes 6, thelower ends of which are provided with Bunsen burners 7. Gas is suppliedto the drum 5 in any desired way. The pipes 6 pass through a suitablebrace 8, which also unites the standards 4 and holds these pipes true atall times. The standards 4 also contain suitable projections 9 and 10,which are perforated and form guides for rack bars 11. The upper ends ofthese rack bars 11 are united by a suitable frame 12, which carries theinverted mantles 13 and these mantles 13 hang from Specification ofLetters Patent.

the frame 12 just as they hang when in use and below the burners 7. Thebar 12 is fur ther supported by pins 14 that run upwardly from a shelf15, which is parallel to the frame 12 and supported by suitable brackets16 fixed to the rack bars 11. These supports 16 are preferably shaped asshown in Fig. l. The rack bars 11 engage segmental gears 17, which arefixed on a horizontally disposed shaft 18, which is mounted in bearings19 and one end of this shaft 18 is provided with a slotted crank 20which receives a bolt 21, to which is connected a link 22 that runs in avertical plane to a second bolt 23 mounted in a slot 24 of a lever 25 ona shaft 26 (for details see Figs. 10 to 12 inclusive) and the shaft 26is suitably mounted in a bearing 27, which is a part of a leg 2. Theshaft 26 also carries a disk 28 with a notch 29, a boss or sleeve 30 andan interrupted gear 31 separated from the bear ing 27 by this sleeve 30.The gear 31, the disk 29 and the arm 25 are all fixed to the shaft 26 bymeans of slots and keys or any other suitable means. As shown in Fig.12, one wall of the slot 29 is radial.

The interrupted gear 31 meshes with a corresponding and largerinterrupted gear 32 mounted on a suitable shaft 33, the ends of whichhave bearings 34 in the legs of the machine, the gears being made asshown in Figs. 3 and 4. From these figures, it is obvious that theshafts 26 and 33 will revolve once in the same time or have the samenum-, ber of revolutions per minute, so that the shaft 26 will revolveintermittently, while the shaft 33 will revolve continuously and thenthe shaft 26 will make half its movement in each revolution continuouslyand then be interrupted in its movement and then make about a quarter ofits movement and will finally make tle remainder of its movement. Theshaft 33 also carries a gear 35, which is fixed thereto and-also to'theinterrupted gear 32, so that the gears 32 and 35 will always revolvetogether. The gear 35 is driven by a pinion 36 on a shaft 37 mounted insuitable bearings 38 in a leg 2. The shaft. 37 is fixed to a collar 39provided with a pin 40 running parallel to its axis, as shown in Fig. 5,and surrounding this shaft 37 and resting against the collar 39 is acoiled spring 41, which is adapted to be compressed in a manner whichwill be described below. This spring 41 enters a recess in a sprocketwheel 42, which is mounted on a shaft 37 and normally runs idle thereon.At times, this sprocket wheel, which has pins 43, is forced toward thecol hit 39, so that the pin 40 of this collar enga a corresponding pind3 on the sprocket wheel 42. The means by which the sprocketwheel 42 isforced, so that its projections l-I-l engage the projection 4.0 is acrank 44, which is mounted so as to turn freely on the shaft 137 andthis crank has a projection 45, that enters a corresponding recess 4L6in the bearing so that when the crank l-it is moved one way or theother, the projection will ride out of the recess 46 and against thebearing 38, at which time the spring ll compressed and the pin 40engages a pin 43. The sprocket wheel [2 runs continuously and whenconnected to the collar 39, in the manner above described, this collarwill. force the shaft 37 to revolve and the rotation of this shaft willrotate the pinion 36, which is fixed to this shaft and through thispinion the entire apparatus is driven.

The crank ist is provided with a suitable slot 47, in which is placed asuitable pin i8, and this pin is fixed in a link 49,which is pro videdwith a handle 50 at its free end. This link 49 is provided with a pin,which engages a spring 51, that runs to a second pin on a leg 2 of themachine. This link 49. is also provided with a third pin 53, which isadapted to take into a recess 29 of the disk 28 and when in said recess,this spring 51 holds the pin 53, so that the link l9 causes the crankst-t to be placed in such a position that the projection 4:5 rests inthe recess 46 of the bearing 38 and thereby prevents the rotation of theshaft 37.

In view of the foregoing, the operation of my improved machine will bereadily un- ('lGl'SllOOtl.

Assuming the parts to be as shown in Figs. 1 and 2, and the burners all.lighted and ready for use, and the mantles 13 in place, the operatorgrasps the handle 50 and raises the same and allows it to move in thedirection of its length under the tension of the spring 51 and until thenotch 45 is out of engagement with the recess 16 in the bearing 38. Thesprocket wheel 42 then drives the shaft 37, as above described, andwhile the pinion 36 drives the gear 35, wl'iich drives the interruptedgear 32, and this in turn drives the second interrupted gear 31 andthrough it the shaft 26. The interrupted gear 31 is so driven that themantles are first raised a certain distance and held stationary for apredetermined interval of time and thereafter the mantles are raisedstill higher or closer to the flame and held stationary another intervalof time, after which they are lowered and held stationary anotherinterval of time and finally lowered to the starting position, thuscompleting the operation. The machine then stops automatically becausethe pin 53 enters the recess 29, thereby forcing the projection 45 intothe recess 46, the mantles are removed, a new set are inserted. and theoperation is continued as before.

It is clear that the number of interruptions and their periods willdepend on the shapes of the gears 31 and andthcirangit lar velocity andby regulating either of these, any number of stops for any period oftime may be provided for. It is im p-ortant that these gears should meshproperly and act as above described, but the pie cise number of stopsand the speed at which these gears rotate can be left to the discretionof the operator.

While I have shown and described one embodiment of my lDYGllflClt, it isobvious that it is not restricted thereto, but is broad enough to coverall structures that come within the scope of the annexed claims.

Having thus described my invention, what I claim is 1. In a machine ofthe class described, a set of burners, removable means for s1 ipportinga set of inverted mantles under said burners, step-by-step means forraising and lowering said mantles with an interrupted motion wherebysaid mantles will be prop erly burned when the machine is in use and anautomatic means for stopping the machine after the mantle has beenraised and lowered a predetermined number of times.
